[PATCH for 2.4] x86_64: Fix missing delay when the TSC counter just overflowed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


I'd seen a problem that *delay functions return in too short delay.
It happens when the lower 32bit of TSC counter is overflowed.
This patch fixes the problem. This is back-port of Andi Kleen's
2.6 fix.
